Extrapolating multi‐decadal plant community changes based on medium‐term experiments can be risky: evidence from high‐latitude tundra

Abstract: For most experimental studies the short‐term responses to manipulation often differ from the long‐term changes in the community composition, dynamics or functioning. Such discrepancy limits the translation of experimental results into key ecological topics such as global environmental change. Here we analyzed plant community dynamics from a 23‐year transplant experiment in the Fennoscandian mountain tundra and explored how well the pattern of responses over the first 12 years of the experiment can predict long… Show more

“…Periodically intense vertebrate herbivory belongs to the natural state of the tundra biome, (Batzli, White, McLean, Pitelka, & Collier, ; Oksanen & Olofsson, ; Oksanen & Virtanen, ; Olofsson et al., ; Saccone & Virtanen, ; Tihomirov, ; Virtanen, ) and the impact of climate change on the arctic vegetation is always modified by herbivore–plant interactions. Thus, changing herbivore impacts have to be considered when interpreting the results.…”

“…). Moreover, in these very low‐productivity environments, the detection of biotic interactions can require experimentation on decadal time scales (Saccone and Virtanen ). It is likely that, in such habitats, the effect of neighboring shrubs in terms of litter production (Buckeridge et al.…”

“…Experiments also suffer from issues of scale (Sandel and Smith ) and tend to focus on short‐term mechanisms that may not drive longer‐term outcomes (Strauss et al. , Saccone and Virtanen ). Despite these and other well‐known limitations (Tilman ), we rely on climate change experiments to provide insight about the future, and in many cases to parameterize and improve models integral for forecasting (Luo et al.…”

“…Experiments, for example, often manipulate key ecological drivers in a simplistic manner, failing to capture the complexity of the real world (Kreyling and Beier 2013). Experiments also suffer from issues of scale (Sandel and Smith 2009) and tend to focus on short-term mechanisms that may not drive longer-term outcomes (Strauss et al 2008, Saccone andVirtanen 2016). Despite these and other wellknown limitations (Tilman 1989), we rely on climate change experiments to provide insight about the future, and in many cases to parameterize and improve models integral for forecasting (Luo et al 2011a, b).…”
